I found a pro-solar energy web site that claims: "Covering 9% of Nevada with parabolic trough systems could generate enough electrical power for the whole of the USA." http://www.power-technology.com/projects/sanfrancisco/ See final paragraph. Nevada is a bit over 110,000 square miles in size. This would make it around 10,000 square miles of land to power the US.
